Tyrell Badd was a homicide detective in charge of the various investigations of the "Great Thief" known as the Yatagarasu. Badd was a detective for many years, overseeing a wide variety of cases and earning a great deal of respect from fellow detectives such as Dick Gumshoe. The bullet holes in his trenchcoat represent the sheer danger of his job. His role in catching the Yatagarasu ended when he testified in a trial that he was, in fact, one of the three people who actually constituted the thief.
